Choose Bolt.new if
- You want full visibility and control while building
- Framework choice matters (Vue, Svelte, Astro)
- You prefer the more mature, predictable platform of the two
Bolt and Emergent take opposite bets on the same technical user: Bolt bets you want to see and steer everything; Emergent bets you'd rather delegate and supervise. Bolt ($25/month) is the transparent workshop — files, terminal, dependencies visible in your browser, your choice of framework, your hands on the wheel. Emergent ($20/month entry) is the autonomous crew — specialized agents plan, code, test and deploy while you review the output, and it builds mobile apps, which Bolt doesn't.
By temperament: if watching the machinery build confidence, Bolt — it's also the more proven platform, with StackBlitz's years of dev-tools pedigree behind it. If results-per-hour-of-your-attention is the metric — and you accept the variance of the category's youngest platform — Emergent. For mobile specifically, Emergent wins by default. And the recurring honest note: non-coders reading this out of curiosity belong on Base44 or Lovable, where neither visibility nor supervision is your job.

Bolt Cloud now includes managed databases, authentication, file storage, logs, secrets and server functions without a third-party account; Supabase remains available for more advanced control.
Emergent includes authentication, database, payments and hosting, and documents React frontends with Node.js or FastAPI backends and MongoDB data. External providers such as Supabase can also be integrated.
Builders can edit the complete project code, connect GitHub, download the project or open it in StackBlitz. The code is portable, although connected hosting and data services may still require migration work.
Emergent states that generated code syncs to the user's GitHub repository and can be exported, deployed elsewhere or continued by an engineering team. Moving the connected runtime services still requires operational work.
Bolt provides an official help center and open Discord community; paid users also receive email support. The support structure is useful, though less extensive than the largest builder communities.
Emergent maintains an official help center and product documentation, but its established peer-support footprint is still smaller and less visible than the category's largest communities.
Bolt supports GitHub, Figma, Stripe and Expo, plus either Bolt Database or Supabase. The range is practical for web and mobile builds, while backend language support remains centered on JavaScript.
Emergent advertises more than 100 integrations and MCP connections across payments, databases, communication, design and business tools. Exact setup and credential requirements vary by service.
Bolt now documents SOC 2 Type II, GDPR/CCPA, encryption, isolated browser execution and automated security review. SSO, audit logs and advanced governance are Enterprise features, and generated-app authorization still needs hands-on validation.
Emergent documents ISO 27001 and SOC 2 Type I certification, with SSO/SAML, role-based access and audit logging for enterprise use. These are first-party claims, so buyers with regulated workloads should verify the applicable plan and reports.
Built-in hosting publishes every project to a free `bolt.host` URL, while paid plans add custom domains and higher traffic limits. Sites can pause when hard free-plan hosting limits are reached.
Standard includes private project hosting, while Enterprise adds managed hosting controls and deployment in the customer's own cloud. Deployment and ongoing iteration consume plan credits.
Bolt supports prompt-first building with no coding required, while still exposing frameworks, source control and direct code editing. Token budgeting and JavaScript-focused architecture become more relevant as projects grow.
Emergent uses a natural-language, multi-agent workflow to build web and mobile applications end to end. It can remove much of the initial setup for non-developers, although reviewing complex agent output still requires care.
Free includes 1M monthly tokens with a 300K daily cap; Pro starts at $25/month with 10M tokens and hosting. Because Bolt repeatedly reads project files, token use generally rises as a codebase grows.
Free includes 10 monthly credits; Standard is $20/month with 100 credits, while Pro is $200/month with 750. A single credit system funds building and platform work, so larger iterations need budgeting.
A prompt can produce a working web app with authentication and database tables in minutes, and Bolt Cloud removes separate database and hosting setup. Larger or more complex apps still benefit from staged prompts and testing.
Frontend, backend, database, authentication, payments, hosting and mobile output can be produced in one workspace, reducing service assembly during an initial build.
Bolt can generate and refine interfaces from prompts and import Figma frames, including team design-system context. Visual consistency still depends on the supplied design direction and component coverage.
Emergent generates complete web and mobile interfaces as part of its full-stack workflow. Its documented strength is end-to-end application completion rather than the fine-grained design control emphasized by design-first tools.
Developers who want to prototype full-stack apps quickly in the browser.
Non-technical business users who need simple internal tools and automations.
These are both developer tools. If you don't write code, start with a full-stack builder instead:
